Christof's Python 3 patches from
https://bitbucket.org/cmeerw/roundup/commits/branch/py3-cmeerw need to
be merged to trunk.

The patches are now in the "py3" branch:

https://bitbucket.org/cmeerw/roundup/commits/branch/py3

(the py3-cmeerw branch contains a few other changes not directly 
related to Python 3)

Anyway, I now get:

141 failed, 644 passed, 354 skipped (with Python 3)
785 passed, 354 skipped (with Python 2)

with most of the remaining failures in the mailgw tests (but I don't 
test MySQL or PostgreSQL)

Great!  Hopefully you can get write access soon (given a Sourceforge
username provided to Ralf as per
https://sourceforge.net/p/roundup/mailman/message/36376896/ ) to start
pushing your fixes to trunk (recall I omitted my gettext fixes from the
patches I pushed to trunk, given the problems you found with them, so
your gettext fixes will need to be integrated with any parts of that
patch that are still relevant for application to trunk).

For mailgw failures it will be necessary to update the patches mentioned
in issue2550970 and get those onto trunk.

These patches are now on trunk.
